Shining light on diabetic retinopathy

A group of scientists in California is trying to develop a cheaper, less invasive way to spot the early stages of retinal damage from diabetic retinopathy, the leading cause of blindness in American adults, before it leads to blindness.

Iron may be a suitable approach for developing novel cancer treatments

Rapid growth of cancer cells and their frequent divisions have their price: Cancer cells need considerably more energy than healthy cells.

Saving limbs with drug-eluting stents

Attempts to treat critical limb ischemia in peripheral arterial disease (PAD) patients with below-the-knee angioplasty are still thwarted by restenosis (the re-narrowing of the artery at the site of angioplasty or stenting), the need for repeat treatments and the continued progression of atherosclerotic disease, leading to tissue death (gangrene) and amputation.

Metastatic bone disease patients can walk in Lazarus' footsteps

Osteoplasty - a highly effective minimally invasive procedure to treat the painful effects of metastatic bone disease by injecting bone cement to support weakened bones - provides immediate and substantial pain relief, often presenting individuals who are suffering terribly with the miraculous so-called "Lazarus effect," according to researchers at the Society of Interventional Radiology's 34th Annual Scientific Meeting.

Helium/oxygen mix helps lung patients breathe easier

New research published in the international journal Chest , by Neil Eves, PhD, finds that people with chronic obstructive pulmonary disease (COPD) who breathed a mix of 60% helium and 40% oxygen during a rehabilitation program were able to exercise longer and harder than those who breathed normal air.

Synthetic biology extends anti-malaria drug artemisinin's effectiveness

In addition to providing a simple and much less expensive means of making artemisinin, the most powerful anti-malaria drug in use today, synthetic biology can also help to extend the effectiveness of this drug.

Saving heart attack patients in the middle of the night

When Joyce Moss recently arrived at Loyola University Hospital with a life-threatening heart attack, it took just 42 minutes to perform an emergency balloon angioplasty.

Pulmonary hypertension in children may result from reduced activity of gene regulator

Too little activity by gene regulators called PPARs appears to be a major player in the irreversible lung damage that can occur in children with heart defects, researchers say.

For first time scientists determine structure of a protein in the living cell

The function of a protein is determined both by its structure and by its interaction partners in the cell.

Research trial call for pregnant smokers

Mums-to-be across the East Midlands are being invited to take part in research that aims to establish whether nicotine patches are safe and effective for pregnant smokers.

New tissue engineering technique may help stem cells generate solid organs

Stem cells can thrive in segments of well-vascularized tissue temporarily removed from laboratory animals, say researchers at the Stanford University School of Medicine.

Angiogenesis inhibitors, study points to limitations, solutions

A new generation of cancer drugs designed to starve tumors of their blood supply - called "angiogenesis inhibitors"-succeeds at first, but then promotes more invasive cancer growth-sometimes with a higher incidence of metastases, according to a new study in animals.

Noninvasive optical device monitors brain blood flow and metabolism in stroke victims

A University of Pennsylvania team has completed the first successful demonstration of a noninvasive optical device to monitor cerebral blood flow in patients with acute stroke, a leading cause of disability and death.

Broccoli and other cruciferous vegetables may protect against asthma, allergic rhinitis and COPD

Here's another reason to eat your broccoli: UCLA researchers report that a naturally occurring compound found in broccoli and other cruciferous vegetables may help protect against respiratory inflammation that causes conditions like asthma, allergic rhinitis and chronic obstructive pulmonary disease.

The obesity paradox

It's called the obesity paradox. Although obese people are more apt to suffer from inflammatory diseases, such as diabetes, heart disease, and stroke, they are also more likely to survive a major attack caused by one of those conditions.

Research brings bioengineered organs a step closer

By now, most people have read stories about how to "grow your own organs" using stem cells is just a breakthrough away.

Two compounds show great promise for cerebral palsy

Two compounds developed by Northwestern University chemists have been shown to be effective in pre-clinical trials in protecting against cerebral palsy, a condition caused by neurodegeneration that affects body movement and muscle coordination.

University at Buffalo designed ventilator can safely sedate ICU patients for less

A new, recently licensed medical device developed by University at Buffalo researchers would introduce into intensive care settings the powerful and effective method of anesthetizing patients that works so well in the operating room.

Investigational protein may reverse neurodegenerative diseases

An investigational protein that transformed normal laboratory mice into super-jocks holds great promise in developing new treatments for neurodegenerative diseases like Parkinson's, Alzheimer's and ALS (Lou Gehrig's Disease), say researchers at the University of Virginia Health System.

Mental fatigue impairs physical performance in humans

When participants performed a mentally fatiguing task prior to a difficult exercise test, they reached exhaustion more quickly than when they did the same exercise when mentally rested, a new study finds.
